Linoleum: For basic cleaning, the best way to clean the surface of the Side Table is to use 1 part dish washing liquid (such as Dawn, etc.) to 1 part water. Do NOT use Windex or other harsh cleaning supplies on the surface, as this could damage or warp the linoleum. For minor scuffs, use linseed oil (boiled or unboiled), which can be found at your local hardware store or online. Apply the oil directly to the affected area and let sit for 5 minutes. Then, using a damp cloth, buff the area in a circular motion. Allow the area to dry completely before using. You may need to reapply and repeat this process a few times to fully remove blemishes. Birch and Walnut: For daily cleaning, use a damp cloth with a dab of dish soap or vinegar. For anything tougher, use vinegar diluted in water. Wipe the surface dry after cleaning, and never leave standing water on the surface for an extended period of time. The surface is made from real wood with a UV sealed, water-based finish and as such, is sensitive to prolonged exposure to moisture or direct sunlight.Steel Legs: The Side Table legs can be cleaned with a damp cloth in warm water. Be sure to dry them off afterwards.
